About Fontana, CA

Fontana is mostly single-family neighborhoods, and the backyards we see range from older one-story houses with a plain concrete patio to newer tract homes where the builder poured a slab off the family room and stopped there. A lot of the calls we get here start the same way they do next door in Rialto. There's a patio that gets used a few weekends a year, and a family that wants it to work as a real room.

That's why a job here usually starts at the back wall of the house. What the slab or deck can hold, and where a new roof can meet the existing roofline, decide most of what we can build before anyone picks out windows.

Services in Fontana, CA

  • Patio enclosures

    Plenty of Fontana houses already have a covered slab out back, and patio enclosures turn that space into a room by closing in the sides under a roof you may be able to keep. I check the cover's posts and how it's tied to the house first, because an enclosure is only as good as what it hangs from.

  • Patio-to-sunroom conversion

    When the slab is sound but the old patio cover isn't worth saving, we build a full sunroom on the concrete you already have. We look at the slab's edges and slope before we plan any walls, because a slab poured for a grill wasn't poured to carry a room.

  • Patio cover installation

    Some homeowners here want a covered spot off the back door now and the option to close it in later. We can build the cover so it's ready to take walls down the road, which saves you tearing it out if you decide to enclose it.

  • Sunroom remodeling

    Older houses in Fontana sometimes come with a room someone added out back years ago that leaks, sticks or just never gets used. We replace the glass, the roof panels or the whole shell and keep what's still solid, so you aren't paying to rebuild what doesn't need it.

  • Three season sunrooms

    If you want a place to sit out back most of the year without running it like part of the house, a three season room is usually a better fit than a fully insulated one. I'll ask how you'll actually use the room before we settle on it.

  • Four season sunrooms

    When the room has to work like part of the house, as an office or a place for the kids, we build a four season room with insulated walls, roof and glass. That means tying into the house more carefully, so we plan it around your roofline from the first visit.

What to know before a sunroom job in Fontana

If your house is inside Fontana's city limits, building permit applications go to the City of Fontana's Building & Safety office, but parts of the Fontana area are unincorporated and fall under the County instead. That's the first thing I check on your address, because it decides which office reviews the plans and whose schedule we're working around. The city also requires every business that works inside its limits to hold a city business license, even one based elsewhere like us in Colton, so it's fair to ask any contractor you're considering about theirs. We're licensed and insured, and when your project needs a permit we prepare the plans, handle the paperwork and set up the inspections.

We work the same way in Riverside and Rancho Cucamonga, and Fontana is an easy run from Colton. What moves the price is mostly the size of the room, whether your slab or deck can carry it as it is, three season versus four season, and how the roof meets the house. The schedule turns on the permit review and on how long the windows and panels take to come in. You'll get the figure for your own room in a written estimate after I've seen the house.

Fontana, CA properties and local conditions

Most of the rooms we're asked about in Fontana would sit on a concrete patio that was poured for chairs and a barbecue, not for walls and a roof. Before we plan anything, I look at the slab's thickness at the edge, any cracks and which way it drains, because those decide whether we build on it as it is, add support along the edge or pour new.

The other thing we look at on every house here is the back wall, with its stucco, eaves and any door or window the new room will cover. How the new roof ties in there is where an addition stays dry or doesn't, so we plan that joint first and build the room around it.

How a sunroom job goes when you call us from Fontana

  1. Call or send the form

    Call (909) 679-6010 or send the form, and we'll set up a time for me to come out to your house. It's best if you can be home so we can talk through how you want to use the room.

  2. I look at your patio

    I come out myself, look at the patio, deck or slab and where the room meets the house, and ask how you plan to use it. Then you get a written estimate, and I'll go over any line in it as many times as you need before you decide.

  3. We handle plans and permits

    When your project needs a permit, we prepare the plans, file the paperwork and set up the inspections with the right office for your address. The city's Building & Safety counter is open Monday through Thursday and closed every Friday, so filings and questions there run on a four-day week.

  4. We build and walk through

    Our crew builds the room, and I come back to walk through the finished job with you. That's your chance to look at every corner and ask about anything before we call it done.

Frequently asked questions

How do I apply for a building permit in Fontana?

The city lists three steps on its building permits page: application and plan submission, authorization and verification, then permit generation. If you've just bought the house, you'll need to show proof of ownership. When your sunroom needs a permit, we prepare the plans and take care of these steps for you.

Who can sign for a building permit in Fontana?

Once the fees are paid, only the contractor on record or the property owner can sign for the permit, and anyone else needs written permission notarized by one of them. The city also says an owner who takes out a permit for a contractor's work takes on the liability for the project, including taxes and personal injury. That's why we handle the permit paperwork ourselves instead of asking you to take it out.

Can I apply for a building permit online in Fontana?

Yes, the city encourages permit applicants to set up an account on the Build Fontana Public Portal, and it now takes permit payments online. Paying that way adds a service fee of 3% plus $0.20 per transaction, or a flat $3.00 per transaction if you choose the ACH bank-transfer option. The counter still takes applications in person if you'd rather file there.

Does the Fontana Fire Department need to review my sunroom plans?

Only if your project requires a fire permit, in which case Building & Safety refers it to the Fire Department. That department reviews the plans and issues the fire permit once they're approved, so it's an extra review to plan around, and we'll tell you if your plans get sent there.

What is the best way to turn a Fontana patio into a sunroom?

Start with the slab and the back wall of the house, because what they can carry and where the roof can tie in set the limits for everything else. Then choose between a three season and a four season room by how you'll really use it, not by what's biggest. Our patio-to-sunroom conversion page walks through the steps in more detail.

How much does it cost to add a sunroom in Fontana?

Your price comes from the size of the room, what your slab or deck can carry and whether it's a three season or four season room, so I don't give a number until I've seen the house. Glass, roof style and whether we can keep an existing patio cover move it too. The written estimate after my visit is free and gives you the figure for your own room.
